Application filed April 20, 1912. Serial No. 692,094.

T 0 all whom it may concern:

Be it known that I, LoUIs N. T. GUERTIN, a citizen of the United States.residing at Xashua, in the county of Hillsboro and State of NewHampshire, have invented new and useful Improvements in Fan Attachments,of which the following is a specification.

My invention pertains to fan attachments for rocking chairs and thelike, and consists in the construction, hereinafter described andclaimed, whereby two kinds of motion are transmitted to a fan incidentalto rocking movement of the rocking chair or other rocking device towhich my improvements are applicable.

In the drawings accompanying and forming part of this specification:Figure 1 is a perspective illustrating my novel fan attachment asproperly applied. Fig. 2 is a vertical section showing the manner inwhich the rockers of the chair are connected with the base which ispreferably though not necessarily employed. Fig. 3 shows the manner inwhich the handle of the fan is connected with the forwardly extendingshaft. Fig. at shows the connection between the two shafts that aredisposed at right angles to each other.

Similar letters and numerals designate corresponding parts in all of theviews of the drawings.

In the preferred embodiment of my invention, I employ a base in the formof a frame 7), and on the side bars of the base I arrange the rockers aof the chair 0 which, 7967' so may be of any construction compatiblewith the purpose of my invention. The said rockers a are provided withupwardly tapered vertical apertures, Fig. 2, and in saidapertures arearranged upright rods 1, pivoted to the bars of the frame 6, and eachequipped with a washer at, a nut 3 and a spring that is interposedbetween said washer and a second washer arranged adjacent the rocker. Byvirtue of this construction the rockers a are strongly connected withthe base, and yet are free to move within certain limits on the base inthe manner common to rocking chairs.

Journaled in suitable bearings 17 on the back of the upper portion ofthe chair is a transverse rock-shaft 16, equipped at 15 with arearwardly extending crank arm, and pivoted to and extending downwardfrom said arm 15 is a pitman 14. This pitman is pivoted at its lower endon a pin 13 carried by a crank arm 13 that is fixed on a transverseshaft 11. The said shaft 11 is journaled in a support 7 connected in afixed manner with one rocker. The shaft 11 is provided at the oppositeside of the support 7, with reference to the crank arm 13% with a pinion6, and intermeshed with the said pinion is a gear segment 5. The saidgear segment 5 is pivoted to and arranged alongside the support 7, andfixed to and extending rearward from the gear segment is an arm 8. Thisarm 8 is pivotally connected to the upper end of a link 9, the lower endof which is pivotally connected to a bracket 10, fixedly mounted on theframe Z). By virtue of this construction it will be manifest thatincidental to oscillation of the rocking chair, the shaft 16 will berocked about its axis through the medium of the train of elementsmentioned, viz: the link 9, the gear segment 5, the pinion 6, the shaft11 with its crank arm 13, and the pitman 14 interposed between andconnecting said crank arm 13 and the crank arm 15.

Disposed above and extending forward from the rock-shaft 16 is arock-shaft 25 which carries the fan cl, the handle of the fan beingsecured as shown in Fig. 3, in a clamp, and the said clamp beingequipped with a wing-nut 29 and socket portions 28 to receive a ball 28on the forward end of the shaft 25, whereby the fan may be adjustablyfixed in various ositions relative to the shaft 25, as occasion demands.The rear portion of the shaft 25 is journaled in a sleeve 20, best shownin Fig. at, and the said sleeve is provided with a depending threadedstem 20, and is also provided with a clutch face 20 Said clutch face isopposed to a complementary clutch face 20 on a bracket 18 that receivesthe stem 20 and the said bracket 18 is positioned on the shaft 16, andis adjustably fixed thereto by a set screw 19. Thus it will be manifestthat the shaft 25 can be positioned at different points in the length ofthe shaft 16, and by loosening the wing-nut 21 and manipulating thesleeve 20, said shaft 25 can be disposed at various angles ofinclination to the shaft 16 as occasion requires, and this withoutinterfering with the rocking of the shaft 25 about its axis.

Fixed by a set screw 24 on the shaft 25 is a grooved segment 23 thatreceives in its groove a cable 26 that is suitably connected at itsupper end to the said segment 23, and is connected at its lower end tothe pin 13. Surrounding the shaft 25 and connected at one end. to thesleeve 20, and at its opposite end to the lateral tubular projection 23on the segment 23, is a coiled spring 22. The said coiled spring 22serves incidental to the oscillation of the chair to rock the shaft 25in one direction about its axis, while said shaft is rocked in theopposite direction by the cable 26 connecting the pin 13 and the segment23. Thus on rocking of the chair the fan will. be swung up and down withthe shaft 25, and also with the shaft 16 to which the bracket 18 isfixed, as before described. It will also be manifest that dining thesaid movements of the chair, the shaft 25 and the fan (Z, the said shaft25 will. be rocked about its axis in the sleeve 20, and hence the fanwill be swung up and down transversely of the chair.

It will be gathered from the foregoing that by reason of the two kindsof motion transmitted to the fan, the person occupying the chair will beadequately fanned and kept cool, and this without effort on the partofsuch person other than the ordinary effort that is necessary to theactuation of a rocking chair.

I have entered into a detailed description of the parts embraced in thepresent and preferred embodiment of my invention, in order to impart anexact understanding of the said embodiment in all of its details. I donot desire, however, to be understood as confining myself to the saidspecific construction, as in the future practice of the invention suchchanges or modifications may be made as do not involve departure fromthe scope of my invention as claimed. For instance in lieu of thespecific base Z), a base of any other description may be employed suchas the floor of an apartment, without involving departure from myclaimed invention. Also, the shafts 16 and 25 may be mounted on anymovable device suitable to the purpose, and may be connected through thepitman 14: and the cable 23 with any other suitable device with respectto which the first-named device is movable without involving departurefrom the scope of my claimed invention.

Having described my invention, what I claim and desire to secure byLetters-Pat ent, is: y

1. The combination of a base, a rocking device disposed upon andyieldingly con nected with the base, a transverse shaft journoeaoarnaled in hearings on the rocking device and having a crank arm, a shaftcarried by the rocking device and having a pinion and also having acrank, a pitman connecting said crank with the first-named crank, a gearsegment intermeshed with said pinion and pivoted to the rocking deviceand having an arm, a link pivotally connected with the said arm and thebase, a bracket on the trans verse rock-shaft, a. sleeve adjustablyfixed on said bracket, a shaft journaled in said sleeve and equippedwith a fan and a grooved segment, a coiled spring surrounding the shaftand connected with the sleeve and the grooved segment, and a cableconnecting the grooved segment and the crank on the shaft that carriesthe pinion and adapted to lie in the groove of the segment.

2. The combination of a rocking device, means with respect to which thedevice is adapted to rock, a fan, coo i erating devices on the rockingdevice and said means for actuating the fan in one manner incidental tothe rocking of the device, and means connected with the fan foractuating the fan in a different manner incidental to the rocking of thedevice.

3. The combination of a rocking device. means with respect to which thedevice is adapted to rock, a shaft join-naled on the rocking device,cooperating devices on the said means and the rocking device for rockingsaid shaft about its incidental to locking of the device, a shaftmovable with the rock-shaft when the latter is rocked and also movableabout its axis independently of the rock-shaft and carrying a fan, meansfor turning the fan shaft in one direction, and means for turning thefan shaft in the opposite direction; the latter means being connectedwith the actuating device on the rocking device.

l. The combination of a movable device, means with respect to which saiddevice is adapted to move, a fan, cooperating devices on the movabledevice and said means for actuating the fan in one manner incidental tothe movement of the device, and means connected with the fan and saidmeans for actuating the fan in another manner incidental to the movementof the device.
